IMP'RovEMnNT IN MACHINES PQR PACKING SALT.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom yit may concern y t Be it known that I, JOHN MoG'nnw, ofWest Columbia, in the county of Mason andState of West Virginia, haveinvented a.ne\v and .improved Machine for Packing Salt; andI do herebydeclare that the following isa full, clear, and exact description of thesame, reference being had to the accompany-` ing drawing forming'a-partof this specification, iu

which- Figure l is a side elevation, with one side of the base-chamberremoved 5. v

Figure2 is a transverse vertical section; and

Figure 3 is ai plan view of the lower ends of the filling-tubes andpacking-hammers.

. This invention has for itsohject the filling of bar- -rels with saltat the place of the manufacture of the same.

vThe,iuventim consists iuhammers xed at the Alower ends offverticalrods, whose upper ends are connected, bya pitman, with a horizontalcrank-shaft Y mounted in a frame thatslides in a vertical guideway, therevolution of the crank operating the packing-hammers, and the slidingframe yielding against the pressure of the hammers upon the salt, soastolift the hammer-maud keep them always ,aboveV the surface of thesalt in the barrel, as the latter graduf ally fills.

Also, in providing the packing-hammers with wedge-shaped projections,for packing salt into the bulges of barrels.

Also, in' 'combining with the packing-hammers,

vtubes for conducting salt into the barrel, and vertically adjustable,in order `that they may be set higher or lower, with reference to thesalt' in the barrel, according as more or less salt is to bedelivered'at each rise of the packing apparatus and in combining, withthe packing-hammers vand filling-tubes, a.- rotating table for thebarrel to stand on, so that the latter may b e turned as it lls, inorder to insure a` packing of uniform density.

AIn the drawing- A is a horizontalA chamber. Y

jt, a conveyer screw, which conducts salt, within the chamber, from thefeeding-,funnel i to thervertical elevator k.

d d are the inclined branches of aspout, which re-r ceive the salt fromthe elevator and conduct it to spouts c c, one at each side of theverticalframe-work B, by which spouts the salt is led throughadjustablelilling-tnbes b b into the barrel.

The filling-tubes are attached to a head, whhh,v is rigidly conuected,bystays m, with the frame 11, which .slides `in vertical guide-ways in theframe-work B.

The filling-tubes are quadrantal in shape, and

placed opposite each other, and between them slide the packingdlammers co, also placed opposite each other, and affixed to the lower extremitiesof vertical rods r r, which pass through the head, and are provided withcross-heads at their upper extremities, which slide in verticalguide-ways within the frame u,

Vand are connected, by pitmen s s, with a crank-shaft, t,

placed horizontally ofthe frame n, passing through slots in the sides ofthe framework B, and made to revolve bythe application of any suitablepower, so as to impart to the hammers'the,reciprocating motion requisiteto packingsalt in the barrel.

By means of pinions 'u on horizontal shafts e, at

the sides of the frame-work B, gearing with racks w i ou the frame n?,the latter` may be set so as tolocatc thek illingtubesaudpacking-hammers at the required height 'within the barrel. This needonly be done at the beginning of` the operation of filling a barrel, as,during they operation, the frame adjusts itself.

The filling-tubes should be placed so that the packing-hammers passbelow their lower ends, and they are adjustable, for this purpose, onthe head.

The barrel isv placed on a table, c,'that is let into the top of thebase-chamber'A, audlafxedto thc upper end of -a vertical shaft, sc,Awithin the base-v chamber, which receives rotation through the'instrumentality of bevel-gearing, which is operated by' a stem from theconveyer screw, so that the barrel turns as it is filling, and everyparticle of the packed salt receives a uniform pressure.

Every time one of the packing-hammers descends, aud meets withresistance from the salt it cozn- -presses beneath it, it rises alittle, lifting the frame at in its guide-way. 'lhe frame'n. carries upwith it the llling-tubes.

A-t every elevation of the filling-tuhes a fresh deposit of salt is leftbehind in the barrel, which, by the revolution of the latter, isspeedily brought beneath one of the hammers and compressed. In thisInauner the hammers gradually travel upward till the bai'- rel is fullQ-It is obvious that the weight ofthe frame u determines the degree ofdensity with whichthe salt is IVhztt I claim ns new, and desire tosecure by Letters Patent, -is- 1. The packing-hammer o, combined withthe slidingr head o1, substantially in the manner described, and for thepurpose of enabling the hammers to lift themselves in the barrel, whilepacking salt therein.

2. The packing-hammers, when provided with wedge-shaped projections a,at their outer und lower corners,.for the purpose of forcing saltoutward into the bulge of the barrel, substantially as specified.

3. In combination with the packing-hammers, the

adjustable filling-tubes b, substantially in the manner and for theobject specified.

4. In combination with the packing-hammers and filling-tubes, therotating table c, substantially in the manner and for the purpose setforth. y

To the above specilicntion of' my invention I have signed my hand this25th day-ot' Merch, 1870.
